Berry-Dedrick phenomenon

Berry-Dedrick phenomenon

the occurrence of typical myxoma in rabbits when injected with a mixture of myxomatosis virus that has been inactivated by heat and viable fibroma virus. The explanation is that the nucleic acid of the inactivated myxomavirus is incorporated into the protein coat of the fibromavirus. The hybrid particles which result retain the coding of the myxomavirus and cause myxomatosis.
